A search for the pair-production of scalar leptoquarks in 1/fb of 7 TeV ATLAS
data recorded at the LHC is presented. Leptoquarks are hypothetical
color-triplet bosons which carry both quark and lepton flavor, and thus decay
to a quark and a lepton, unlike any of the Standard Model particles.
Leptoquarks arise from many beyond the Standard Model theories. The channels
examined in this analysis require at least one leptoquark decay to an electron,
which includes the final states eejj and evjj. No excess of events is observed,
thus limits on allowed leptoquark masses are determined. We exclude at 95%
confidence level the production of first-generation scalar leptoquarks with
mass m < 660 (607) GeV when assuming a branching fraction of leptoquark decay
to an electron of 1.0 (0.5).
